The benefits of raising levels of diversity and inclusion in STEM education, research settings and workplaces were highlighted by many contributors to our inquiry. The Government, UKRI, other research funders, industry and the education sector have led and participated in many worthy inquiries, reports and initiatives. Yet progress has been limited at best. The status quo must not be accepted by those with the ability to drive change. It is not simply a legacy problem that will fade as society becomes more diverse. Action must be taken that truly moves the dial. The Government should make improving diversity and inclusion in STEM—and indeed in all aspects of society—a central part of its day-to-day activities and future agenda. It’s not just good for business, it is fundamentally about being fair, and doing the right thing. The education and research sectors must follow the Government’s lead and take a systemic approach to the challenge, making the STEM ecosystem in the UK a beacon of good practice when it comes to addressing under-representation.
